HIGH-SPEED RAILWAY.

Application filed March 7, 1924. Serial No. 697,441.

To all whom it may concem:

Be it known that I, KURT WIESINGER,

- citizen of Germany, residing at Zurich-7,

Switzerland, have invented new and useful Improvements in High-Speed Railways, of which the following is a specification.

The highspeed railways hitherto known are either railways with special track and superstructure, or standard railways. The

special railways have their own tracks after the manner of elevated railways, and the initial costs of these are considerable. The railways themselves are therefore wasteful, and they have not stood the test.

The standard railways with high speed use a reinforced superstructure of normal main lines, as, owing to the danger of derailment due to their high speed, their cars must be very heavy. Consequently the initial cost of such railways with two rails, and particularly the cost of upkeep, is too high.

. parts projecting from the side wall of the Owing to their wastefulnessthey have not been able to be introduced.

The invention here described is intended for the construction of a high speed railway with a maximum speed of about 100 m/s, or 360 km/h, employing normal rails and sleepers. The plant is that of a standard railway, on whose rails the cars are positively guided, so that the danger of derailment is entirely eliminated, and the weight of the cars is reduced to a minimum by the right build of the same.

The invention is illustrated by Figs. 1 and 2. Fig. 1 is a lateral view of a train driven, for example,- transverse section.

The front car is designated by 1, the trailers by 2 and the rear car by 3. The length of the train is determined by the number of trailers 2. All the cars are coupled so closely that at the coupling point there can be no interruption of the streamline current set up by the whole train.

The cars, which are suitably built for keeping the surface small with transverse section either round or flattened below, are mounted on springs opposite the axles 4, which each support two Wheels 5 revolving independently of each other. The wheel body 6 of the cars are enveloped in the lining 7 somewhat similar to the streamline, in order to reduce the atmospheric resistance of these parts to a minimum as well. The wheels 5 engage with their high flanges unby a propelleryFig. 2 is a der the heads of the rails 8, which are in clined well inwards, so that the cars are positively kept on the rails.

In the case described above the driving power is supplied, for example, by an airship motor 9wl1ich actuates a slow-acting adjustable propeller. Of course any other kind of drive or power engine could be employed. At the front of the train there are head-lights 10 for lighting the track, and windows 11 for observation purposes.

Bymeans of the invention here described a high speed railway is created which even at a speed of 100 m/s or 360 km/h is economical and therefore worthy of construction.

By the automatic run of the cars the axle,

pressure can be reduced to 2000 or 3000 kg, as against the present 16000 to 20000 kg. in

Europe and over 30000 kg. in America. This isa point of great importance, as all the dynamic strains increase during the journey, in the first place with the moved weight and in the second with the square of speed. For the same strains on the superstructure the moved weight is therefore to be diminished with theEsqu'are of the s eed of travel. This can only be done in stan ard railways by special .light constructions (aluminium-and magnesium-or similar alloys) if the cars are secured against derailment by their automatic run, and the engine output is reduced to a minimum with the least resistance to motion.

All these claims are fulfilled by the invention herein described.
